SCRAPER-SUPPORT FOR SCREENS FOR FURNACES.

SPECIFICATION` forming part of Letters Patent No. 245,491, dated August 9, 1881. Application led January 17', 1881. (No model.)

To all whom it may concern Be it known that I, EDWARD C. HEGELER, a citizen o-t the United States, residing at La Salle, in the county of La Salle and State of Illinois, haveinvented certain new and usefulV Improvements in Scraper-Supportsin Connection with Screens for Zinc-Furnaces, of which the following is a specification.

The screens, in connection with the scrapersupports, are intended to protect the workmen from the heat ofthe furnace, and at the same time furnish supports for the Scrapers used in cleaning the retorts. The heat before the i'urnace is very great when the retorts are opened and the residue ot' zinc ore and coal is heilig removed. rIhe retorts are arranged in checkrows horizontally and verticallyalong the front surface ot" the furnace. There are narrow vertical openings between the screens, just Wide enough to operate the scraper through, which openings are adapted to be broughtin line with the vertical rows of retorts in cleaning them. The scral'wr-supports are 'arranged within the vertical openings7 and at such distances apart as to correspond with the lower edges of the horizontal rows ot' retorts. The supports may be provided with an anti-friction roller or not, as desired. The screens and the scraper-supports are attached to a car or truck, which is run along upon a track parallel with the furnace. The car 1n ay he so constructed as to run along upon a track upon the ground, or so that its supporting-wheels may run on two rails overhead, or one above and one below the car.

The accompanying drawing illustrates the invention.

Figure 1 is a perspective view of a cnr upon atrack, with the screens and supports attached, placed in front of a zinc-furnace.

A is the screens; B, the openings, c being` small anttfriotion rollers on the supports O. D is the truck.

The openings B may be formed between vertical bars of an iron frame attached to the car, and the screens matt7 be hung upon suoli frame, so as t0 cover Iall parts except the openings. It' the car is ina-de longenough to furnish space for two or more workmen, the vertical npenings should bejust far enough apart to correspond with the vertical rows of retorts.

The scraper is a long iron rod provided with a hook-shaped device at the end, adapted to scrape out the interior of the retort.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A truck, D, having an upright frame attached to one side, with openings B, supports O, and screens A, all arranged to opera-te substantially as set forth, and Jfor the purposes described.
